OK. I am getting used to the idea that I am not going to build a 393/408. Just isn't really in the budget when you can get a complete bottom end rebuild for only 410 bucks from summit. (Plus cam kit of course) So, are cams for a 302 that list a W pattern, also good for a W? Is the lift, overlap, separation and duration calculated for the narrower block of a 302? Or is the only real difference the firing order?
